Do you mind adding the build instructions to the README so I can run it locally? Rails holds my hand with coffeescript and I dunno anything just from looking at the Makefile.
Basically just running 'make' will produce all the needed files in output/. Then you can use 'python -m SimpleHTTPServer' from the output server, and open http://localhost:8000/ in your favorite browser.
For make to run correctly you'll need the haml, sass, and juicer gems installed and in your path.
